Abstract: Echo cancellation is carried out on a received demodulated analog signal. The apparatus comprises an analog transversal filter, a computing circuit for generating the direct coefficients a1 to ar and, eventually, feedback coefficients b2 to bm of an analog transversal filter. The input of a computing circuit is connected to the input of an analog transversal filter. The computing circuit is comprised of an analog-to-digital converter, whose output is connected to a self-adaptive digital transversal filter. The values of the digital transversal filter multiplication coefficients are applied, as coefficients, to the multipliers of the analog transversal filter. The optimization criterion is that of the mean quadratic error. The convergence algorithm is that of the gradient. The iterative correction may be carried out at each step on the digital transversal filter's group of coefficients. Or, it can be carried out cyclically of each of the digital transversal filter's coefficients. Variations of the self-adaptive digital transversal filter are described.

Abstract: Procédé et dispositif permettant d'optimaliser les allocations de ressources, suivant un cheminement à l'intérieur du polytope spatial de solution (50) plutôt que sur la surface (comme c'est le cas pour la méthode simplex), et plutôt qu'à l'extérieur du polytope (comme c'est le cas pour la méthode ellipsoïde). Chaque approximation successive du point de solution (53), et le polytope, sont normalisés de sorte que le point de solution se trouve au centre du polytope normalisé. La fonction objective est alors projetée dans l'espace normalisé et l'étape suivante est effectuée à l'intérieur du polytope, dans la direction de descente la plus inclinée du gradient de la fonction objective et possédant un ordre de grandeur permettant de rester à l'intérieur du polytope. Ce processus est répété jusqu'à ce que l'on parvienne par approximation à une valeur proche de la solution optimale. Ce procédé d'optimalisation est suffisamment rapide pour être utilisé dans des systèmes de commande en temps réel qui requièrent une optimalisation plus ou moins continue des allocations dans un environnement se modifiant sans cesse, et dans des systèmes d'allocations qui étaient jusqu'à présent trop vastes pour permettre une mise en oeuvre pratique par des procédés de programmation linéaire.
